I have still have the mammoth task of graduating from uni,but thank goodness its not required! The flight sim is straightforward enough,slightly stressful because u are being assessed.Plenty of folk get through the selection with little flying hours. But they have to show the maturity and desire(as do everyone else anyway) to sell themselves as potential captains. The flight sim just requires good instrument scanning and listening to everything the guy says to you in the brief and in the cockpit!!
